Solution structure of RIG-I C-terminal domain
Overview
A DExD/H protein, RIG-I, is critical in innate antiviral responses by sensing viral RNA. Here we show that RIG-I recognizes two distinct viral RNA patterns: double-stranded (ds) and 5'ppp single-stranded (ss) RNA. The binding of RIG-I with dsRNA or 5'ppp ssRNA in the presence of ATP produces a common structure, as suggested by protease digestion. Further analyses demonstrated that the C-terminal domain of RIG-I (CTD) recognizes these RNA patterns and CTD coincides with the autorepression domain. Structural analysis of CTD by NMR spectroscopy in conjunction with mutagenesis revealed that the basic surface of CTD with a characteristic cleft interacts with RIG-I ligands. Our results suggest that the bipartite structure of CTD regulates RIG-I on encountering viral RNA patterns.
